In experiments in which hunger in Large WhitexLandrace boars was measured by conditioning them to press a panel to receive 7-g rewards of food, it was concluded that restricting pigs to low food allowances results in a high level of hunger throughout the day. It is suggested that commercial food allowances for pregnant sows and boars, whilst meeting production needs, do not satisfy motivation, and that the resulting hunger may act as a major source of stress under certain housing conditions.
